Dear all, I was trying to test the performance of the VPP Host Stack, compared to the one of the Linux kernel TCP/IP stack. In particular, I was testing the TestProxy application [1] and compare it with the simpleproxy application available at this URL [2].
My setup is composed of a server1, which runs the VPP test proxy application attached to two physical interfaces (dual-port Intel XL710 40GbE NIC). The application listens to TCP traffic on a given IP1:port1 (interface 1) and forwards it to a "backend" server listening on another IP2:port2 (interface 2). Another server2 (same NIC) is running both an iperf3 client, which sends traffic to the proxy at IP1:port1 and an iperf3 server, which receives traffic on IP2:port2. Both iperf3 client and servers are running in two different netns on server2 [3]. The VPP startup configuration that I used is the following [4]. The configuration works fine, however, these are the results that I got: VPP Test Proxy (VPP) - 1.50 Gbits/sec Simpleproxy (Linux kernel) - 9.39 Gbits/sec I am wondering if there is something wrong with my setup/configuration, I am quite new to VPP. Thank you in advance.
